To all whom it may concern;

Be it known that I, WARREN IkTAYLon,

of Stamford, in vthe county of Fairfield and. State of Connecticut, haveinvented certain new and useful Improvements in Means for Securing Looksto Doors; and I do hereby declare the followin to be afull, clear, andexact description 0 the invention, such as will-enable others skilled inthe art to which it liadppertains to make and use the same;

y invention relates to'an improvement in means for securing locks todoors and par ticularly to the doors of safe deposit boxes. It iscustomary, when a safe deposit box is surrendered by the renter thereof,for the custodian of the boxes to replace the lock witha lock having adifierent combination, for. preventing the box from being opened by akey used with the old or former lock.

Heretofore locks have been secured to the doors. of'the boxes by meansof screws passing through the lock case and into the door,

and one of the difficulties experienced by the safe deposit companies inremoving a lock and replacing it with another, is the fact that thelocks which. were applied by the safe maker at the time the boxes wereerected, were more or less adjusted each to its individual door, henceit frequently happens.

that the .screw holes in the lock cases do not perfectly aline with theholes in the door, so that in screwing the lock down tight the screwswill draw the nose or key cylinder of the lock to one side and thus bindor strain thekey hub or the lock bolt and prevent or impair theoperation of the lock.

The object of this invention is to provide ,means whereby the locks maybe readily,

easily and quickly exchanged without the employment of screws or otherfastenin devices passing through the-lock case,'an my invention consistsinthe' parts and combinat-ions of parts as will be more fully described.and pointed out in theclaims.

- In the accompanying drawings, Figure 1 .is a view in elevation oftherear face of a door showingthe lock secured thereto. Fig. 2 is aview 1nside'elevation, part of the door being broken away. Fig. 3 is a view inend elevation. liigs. 4, 5 and 6 are similar views of a modified formand Figs. 7 and 8 are views of another modification.

1 represents the door of a safe deposit box or other receptacle providedwith a cylindrical hole through same for the passage of consequentlyconceals the door is thick, so that when the lock 3 is applied to therear faceof'the door, the front end of the nose orliey cylinder will beapproximately flush with the outer surface of the door. v I

Thedoor is provided on its rear face, near its outer free edge with agrooved adapted to receive one end of the steel or other metal strap 5.This strap is preferably as'wide as the lock case, and is bent at itstwo ends to overlap and snugly fit the front and rear ends of the lockcase. The bent front end 6 of this strap 5 is slotted as at 7 for thepassage of' the bolt 8 of the lock 3, and the portion thereof within thegroove 4; in the rear face of the door, is provided with a screw holefor the passage ofthe screw 9, which is passed through the ed e of thedoor, and is 5 when the door is closed. The rear bent'end 1Q of strap 5.is

bent at ri 'ht angles as at 11 to rest against the rear face ofthe doorand is provided with a screw hole for the passage of a screw 12 into thedoor, the hole in the end 11 of the strap being sufliciently largetopermit the screw to be screwed Home without-imparting any lateralstrains to the strap."

The strap is preferably so constructed that some pressure is required toseat the. end 11 thereof against the door, hence when secured, itclosely and snugly embraces the .lock with a yielding pressure and holdsthe same solidly in 'position, the bolt, and nose or key cylinder of'the lock, preventing any lateral movement-in the pocket formed by thestrap. The front end of the lock 'is preferably provided with a notch 13and the strap'with a rib 14, adapted to register with said notch forcentering or properly alining the lock.

To apply the look too door, the strap is first placed-in pom'tion overthe lock, with the bolt 8 projecting through the slot 7 in the frontbent end 6 of the strap 5, after which the nose or key cylinder 2 isinserted in the hole in the door, and the lock with the strap therein,then pushed or forced against the door. The hole in the door and thenose or cylinder of the lock, locate thelatter definitely without anypressure whatsoever except directly toward the door. This inwardmovmncnt of the lock and strap, carries the bent end 6 of the latterinto the groove in the rear face of the door and it is secured V thereinby the screw 9. After the strap has been secured at its front end, itsrear .bent

end 11 is forced into contact with the rear face of the demand securedby the screw 12.

To remove a lock the screw '12 is first re moved, then screw 9, whichreleases the lock and strap and permits the lock to be detached from thestrap.

In the construction shown in Figs. 4, 5 and 6, I have provided the innerface of the door with an undercut roove 15 and the front end of thestrap with-an inclined lip 16 adapted to engage the inclined wall of theundercut groove, and be retained in contact therewith without the aid ofa screw, and in Figs. 7 and 8 I have provided grooved lugs 17 projectingfrom the inner face of. the

door, which are engagedby outwardly prothe passa e of the lock bolt, andmeans for securing e two ends of the strap tothe rear face of 2. Thecombination with a door having a hole through same and a lock having :anose or key cylinder adapted to rest in said hole, of a stra embracingthe rear face and two ends of the lock and secured at-both ends to therear face of the door.

3. The combination with a door having a groove in .rear face and a holeextending through the door and a lock having a nose or key cylinderadaptedto rest in said hole, a

of a strap embracing the two ends and rear face of the lock, thefront'end of saidstrap resting in the screw securing t e rear end ofsaidstrap to the door.

5; The combination with a door having a groove in its rear face, and ahole extending through the door,-and a lock having a nose or keycylinder resting in said hole, of? an elastic strap embracin rear'faceof the lock, t e front .end of said strap being secured within thegroove in the door by a screw, and means securing the rear end of thestrap to the door.

. In testimony whereof, -I have signed'thi specification 1n the presenceof two subscribing witnesses,
